The Aussie actor has been a regular on TV screens since the mid-90s and almost cracked the big time in Hollywood thanks to roles in Body of Lies  alongside Russell Crowe and The Great Gatsby  with Leonardo DiCaprio.
But after a hellish few years, for which the actor only has himself to blame, Colosimo is now facing jail time after another run-in with the law.
It’s a sad tale of a falling star whose downward spiral began in 2007 when his partner off 11 years, Jane Hall, ended their relationship.
A messy and very public court battle followed as the two actor’s fought over a property worth $890,000 in Northcote where they lived together and raised their daughter, Lucia.
As the case dragged on, Colosimo landed the role of Alphonse Gangitano in Channel Nine’s Underbelly in 2009.
He was nominated for a Logie for his portrayal of the underworld figure nicknamed the “Black Prince of Lygon Street”, but has found the popularity of his character hard to shake in the years since.
“I played Alphonse for two weeks and that rides me every f**king day,” he told TV Tonight, “Every day, in a good way and a bad way”.
